RING FOR PIPE-COUPLINGS.

Specification of Iletters Patent.

Patented May 22, 1906.

Application filed November 10, 1905. Serial No. 286,650.

To aZZ whom it may concern.-

Be it known that I, WILLIAM W. PRICE, a citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Rings for Pipe-Coup lin s; and I do declare the following to be a fill clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accomdrawings, and to the figures of refer ence marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in coupling-rings for pipejoints.

The invention consists in a two-part ring of the above type havin the particular constructions and assemb ed in the manner shown and described. The two parts of said ring are given their requisite formation by means of suitable dies, and when assembled the outer member of-the ring acts as a brace or reinforcement of the inner member, and thus provides a ring having a maximum amount of strength and durability. In addition to the above important advantage the work of constructing the ring is greatly facilitated and the expense minimized.

Preceding a detail description of the invention reference is made to the accompanying drawings, of which Figure 1 is a bottom plan view of my improved two-part coupling-ring, a portion of the same being broken away. Fig. 2 is a cross-sectional elevation of the same. Fig. 3 is a side elevation.

In a detail description of the invention, similar reference characters indicate corresponding parts.

The coupling-ring is essentially constructed of pressed steel or plate of suitable strength, dependent upon the size or diameter of the ring. The blanks from which the two parts are constructed are given their requisite formation by means of suitable dies and when so formed consist of inner and outer members 1 and 2, which are assembled and rigidly united in the manner shown in the drawings. The inner cylindrical member 1 has one edge projected outwardly and laterally to form a flange 3 and the other edge extended inwardly to a greater extent to form the flange 4:, which terminates in an extension 5, surrounding the pipe-opening of the ring. The outer member of the ring is formed to provide a cylindrical wall 6, which lies on the outer side of and rigidly in contact with the wall 1 of the inner member, and the said outer member further has an outer tapering wall 2,

which converges and meets the inner wall 6 at the edge thereof where it is firmly engaged. The two walls 2 and 6 of said outer member are thus brought together to engage the outer flange 3 of the inner member of the ring. The outer ring or member is made slightly smaller in diameter than the inner ring or member, and the two are brought together or forced under suitable power, one into the other, and the flange 3 is turned up a suitable extent to rigidly lock the outer member, as at 9 and at the body thereof. The outer member of the ring has two series of bolt-openings 7 and 8, the latter'providing for the passage of the bolts entering the holes 7. The bolts are not shown; but it will be understood that there are two of these coupling-rings employed to connect or form a pipe-joint, and the bolts referred to are used to make such connection.

Having described my invention, I claim- 1. A pipe-coupling ring consisting of two members formed from sheet metal, the inner member having a circumferential flange projecting outwardly from one end, and an inwardly projecting circumferential flange which terminates in a laterally-extending flange surrounding the pipe-opening, the outer member having a cylindrical wall which lies adjacent to the body of the inner member, and an outer wall which converges and meets the cylindrical wall, the said converging walls engaging the outward flange of the inner member where they are secured, and the said outer member having bolt-holes, substantially asspecified.

2. In a coupling-ring for pipejoints, two members constructed from sheet metal, the inner member having at one end an outwardly-extending flange, and the other end projected inwardly and terminating in a flange surrounding the pipeopening, the

In testimony whereof I afiiX my signature 1n presence of two witnesses.
